    Abstract: PROBLEM TO BE SOLVED: To provide a coated cemented carbide insert (cutting tool) useful for wet or dry milling of steel particularly under high cutting speed, milling of hardened steel, and copy milling with a rapid feed of tool steel. SOLUTION: The cutting tool insert is characterized by cemented carbide body including WC, NbC and TaC, a W alloy Co binder phase, and coating including an innermost layer of TiC x N y O z forming equi-axial particles, a layer of TiC x N y O z forming pillar-shaped particles, and a layer of α-Al 2 O 3 .

    Abstract: PROBLEM TO BE SOLVED: To provide a coated cemented carbide body which can evade or reduce problems in the preceding technology, and to provide a method of using the same. SOLUTION: A coated sintered cemented carbide body includes: a cemented carbide body 200, a first layer 202 adjacent the cemented carbide body, the first layer including Ti(C, N) and having a thickness of from about 3 to about 20 μm; an alumina layer 214 adjacent the fires layer, the alumina layer including α-Al 2 O 3 or κ-Al 2 O 3 and having a thickness of from about 1 to 15 μm; and a further layer adjacent the aluminum layer of a carbide, carbonitride or carboxynitride of one or more of Ti, Zr and Hf 216, the further layer having a thickness of from about 1 to 15 μm.

    Abstract: The present invention relates to a coated cemented carbide insert (cutting tool), particularly useful for wet or dry milling of steels at high cutting speeds, milling of hardened steels and high feed copy milling of tool steel. The cutting tool insert is characterised by a cemented carbide body comprising WC, NbC and TaC, a W-alloyed Co binder phase, and a coating comprising an innermost layer of TiC x N y O z with equiaxed grains, a layer of TiC x N y O z with columnar grains and a layer of ±-Al 2 O 3 .

    Abstract: The present invention relates to cutting tool insert consisting of a tungsten carbide based hard metal substrate and a coating. The hard metal consists of about 4-15 wt-% binder phase with face centered cubic structure and a composition of 35-65 wt-% Fe and 35-65 wt-% Ni in addition to dissolved elements. As a result, inserts have been produced with at least as good performance in machining as conventional state-of-the-art inserts with Co-based binder phase. The insert can be applied in milling and turning of low and medium alloyed steels as well as stainless steels.
